Hardware SD Card Slot not working with certain SD Cards

[Alan Treecko]

I have 3 SD Cards I used on this.
Sandisk 8GB SD Card - Works, No errors
Sandisk MicroSD Card Adapter with 16GB MicroSD Card - Works, almost always shoots an error.
Sandisk 32GB SD Card (I got this yesterday.) - Never works, always shoots either "SD Card is copy protected." or "Cannot detect SD Card." When it works, it doesn't.
I have tried all SD Cards on my brothers 3DS XL and it detects it just fine.
So I guess its the slot? Any how to replace with a board you can buy?

compatibility has been a hit and miss for me, although as far as i could tell it was consistent through consoles.

the only issues i've had is a chinese ov brand 32gb micro sd not reading at all, but working with my phone and windows, and one old adapter that was very unreliable, regardless of which micro sd was used.

it looks super easy to replace!
